o the delight of dog lovers, cities and states have begun passing laws to allow dogs to join patrons on restaurant and bar patios. Many diners have simply asked, “Wait, that was illegal?”Sure, the United States doesn’t have the rich history of outdoor dining of say, Paris, where pooches are almost as common as croissants at outdoor cafes. But when the weather is pleasant, it’s fairly common to see people settling in for an outdoor beer with their dog at their feet. And as U.S. culture shifts to become more pet-friendly, the numbers suggest it will only become more common.Pets are increasingly an important part of many people’s lives. U.S. spending on pets has risen from $17 billion in 1994 to an estimated $72 billion in 2018. The number of craft breweries also has skyrocketed since 2010, expanding the number of spots with a dog-friendly atmosphere.But in many places, health codes simply don’t allow dogs other than service animals to be present at restaurants and bars. Just nine states have laws that allow canine companionship in such places. Many proprietors across the country have been allowing dogs anyway, with owners at worst ignoring the law and at best believing they were operating in a gray area.
